Thadeo is a 23 year old Mercenary for hire who works as a member of Vindice, the gang from the big 5 gangs of northern Avnice who control East Blue Light and it's Red Light district. Thadeo works primarily to pay the medical bills of his last living relative, a comatose woman in a hospital whom he’s never actually spoken with.

He is commissioned by Elena and the rebellion to find and rescue her mother, the political leader of the rebellion, after he kidnaps her as part of a "ghoul job" or a situation where the person hiring the mercenary is secretly acting on behalf of another, anonymous payer. This mistake leads Thadeo down a path that will change him and Avnice forever.

Thadeo is also a programmer who created a program/mod called the Brainspeak algorithm which allows Senergy Reactors to communicate with their Machine Art mentally. Virtually no one knows the identity of the NoTrace, but the hunt for him begins when rumors spread that he is the true killer of the Veiled Maiden's pet, Makkura the Haymaker.
